Rolling Display On Some Games??
boardjunkie:
Sync has nothing to do with the pix filling the screen. Its just there to stabilise the image. If you can't move the image up enough with the v pos control, there might be a jumper on the board to move it more. Maybe the modeline yer using is causing the problem...
Just for anyone following this thread....the monitor he has is H-rex's version of a Sony PVM monitor.

I'm not sure if there is a jumper on the chassis pcb for this as I never got a manual with it :(.

Is that a good thing?. What is H-Rex?
While we're on the subject of this monitor it's there anything i can do to boost the brightness and more so the contrast??. Whilst this is easy enough to fix for a PC (just use ATI CP) it's not for using a retro console. The picture isn't dark persay but I have the contrast as high as the pot will go but have always liked more contrast, is there a way to achieve this?

H-rex=Hantarex.
Your monitor should have a push switch on the back near the db9 input connector. Set that to "analog" and see if that takes care of it. I think its prob'ly set to TTL now and wants to see hotter video input signals.

As far as the vertical problem....you may have capacitors due for replacement if it has high hours of useage.

Damn sorry, i got my threads mixed up. I have actually been talking about the problems im having with my Pentranic CGA 15khz Chassis CH-288-S26A monitor not the Hantarex i have ::) sorry. Everything bar my first 2 posts is regarding the Pentranic not the Hantarex. So its on my new Pentranic that ive noticed that since spliting the sync's that there is a boarder at the top of the screen with the vertical shift pot turned all the wat up, but as you said it might be the Monitor_spec line that is causing that, I take it there isnt a jumper on this monitor to shift the screen up more?
It is actually this Pentranic monitor that i would still like to increase the contrast still, and as i said its acceptable at the moment but i have it turned all the way up and always like most contrast on my games. Is there a way to acheive this for the Pentranic?

I've never been a huge fan of the Hantarex stuff (as found in arcade machines), but that looks like a damn nice monitor. Lots of flexability and inputs. Want....
